BroadcastReceiver Android中的locationManager.requestLocationUpdates

如何解决BroadcastReceiver Android中的locationManager.requestLocationUpdates

我想在后台接收用户位置并对其进行一些数学计算。然后向用户发送通知。我不知道如何管理locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,locationListener)，因为ActivityCompat.requestPermissions(activity: this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION},1);需要活动，而broadcastReceiver中没有活动。

这是我的代码：

public class AlarmReceiver extends broadcastReceiver {
    private static LocationManager locationManager;
    private static LocationListener locationListener = new LocationListener() {

        @Override
        public void onStatusChanged(String provider,int status,Bundle extras){
 
        }

        @Override
        public void onProviderEnabled(String provider) {}

        @Override
        public void onProviderdisabled(String provider) {}

        @Override
        public void onLocationChanged(Location location) {
            //do some math on loacation
        }
    };

    @Override
    public void onReceive(Context context,Intent intent) {
        locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

        if (ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

                // ask for permission

            ActivityCompat.requestPermissions(this,1);


        } else {

                // we have permission!

            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,locationListener);

            }
    }


    @Override
    public void onRequestPermissionsResult(int requestCode,@NonNull String[] permissions,@NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode,permissions,grantResults);

        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

            if (ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)

                locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,locationListener);

        }

    }
}

和MainActivity：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }



    @Override
    protected void onDestroy() {
        Intent intent = new Intent(this,AlarmReceiver.class);
        intent.putExtra("NotificationText","some text");
        PendingIntent pendingIntent = PendingIntent.getbroadcast(this,3,intent,PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP,pendingIntent);
        super.onDestroy();
    }
}
